HEA'rlNc-FURNACE.

SPECIFICATION forming part of Letters Patent No. 248,493, dated October 18, 1881,

Application filed February 10, 1881. (Model.)

To all whom it may concern:

Be it known that l, WILLIAM H. MOORE, a resident of the city ofPortland, in the county of Multnomah, State of Oregon,having invented certain new and useful Improvements in Heating-Furnaces, ot which the following is a speciiication.

Myinvention relates to that class of heating devices known as hot-air furnaces;77 and it consists in certain particulars of construction and combinations of parts, which will be more fullydescribedin theensning specication, and particularly pointed out in the claims at the close thereof.

In the annexed drawings, Figure l is a front elevation of my improved furnace. Fig. 2 is a plan view of the top of the furnace, showing the pipes. Fig. 3 is a longitudinal vertical section, showing the fire-box and arrangement of check-plates and cold-air passages in back part offurnace; and Fig. et is a viewin vertical section through the back part of furnace, showing the arrangement of check-plates and cold-air passages.

A in Fig. l represents the body of furnace, it being ot' the shape shown, Wider at bottom than top.

S represents the fire-box, and k represents the cold-air entrance in front ot' furnace.

d d d d d l are apertures in the sides of the ire-hox S, and the cold air coming in through front entrance, k, and between side of furnace and through the apertures d d d d d d prevents excessive heat, and preserves the parts of furnace otherwise likely to burn out from doing so.

B B represent pipes on top of the furnace, and extending the entire length of furnace, and beyond, on each end and outside of brickwork, they are connected with each other by pipes O O, one on each side. They,inturn,are connected in front with central pipe, D, which conducts the smoke, &c.,from the furnace into the chimney.

Eis the throat or smoke-exit when direct draftis in operation. Its upper cud tits into pipe D, and its lower end into bodyofiuruace A. Placed in throatE is damper c, revolving therein, as shown in Fig. 3,one end being pivoted in throat E, and the rod rextendingalong thefurn ace-bod y directly under central pipe, D, out beyond the front of the furnace, a handle, f, being formed on that end, by which it can be operated from the front of the furnace. Asuitable bearing on top of frontof furnace retains it in position.

G G are pipes which connect with pipes B B, and these pipes G G connect and lit into pipes H H, which lead from and lit into the back part of furnace-body, as shown in Fig. 3.

Draft-checks I I are adjustable caps litted in the front ends of each pipe B. They are in skeleton formthat is, the part fitting inside of pipes B. They have a cap provided With a handle, h, and can be adjusted close up to the Y operating as a check-plate. These checks K K K are for the purpose of checking` the draft and creating a more intense heat in back portion of furnace-body.

l l in Figs. 2 and 3 are adjustable caps fitted into lines H H, and are for the purpose of allowing the accumulations of soot, 85e., to be cleaned out from the ues when desired. In connection with the draft-checks I I the whole arrangementof pipes can be cleaned outat will. The operation of my furnace is as follows: When thc damper c is turned olf the heat and smoke, instead of going out at throat E, goes down and out at pipesH H into thepipes GG, thence into B B, thence into pipes O O, through pipe D, and into chimney. During this opera. tion these pipes on top of the furnace become powerful radiators of heat, and more warmth from thefurnaceisconsequentlyobtained. The check-plates K K K restrain the draftand hold the hot air until theentire back partoffurnace becomes heated. The cold-airpassages JJ also produce more heat in the building by the cold air passing through against their heated surfaces, thereby becoming hot air.

The draft-checks I I are avery important feature in my invention, as by means of them the draft of tne furnace can he regulated by adjusting them from orinto the pipes B B, and

IOO

they perform the important sanitary function of takinginto thefurnaee foul or obnoxious air from the cellar or basement in which the furnace may be, and when it is necessary1 to clean out the pipes they can be taken out and the pipes cleaned.

Having described lny invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In an air-heating furnace, the combination, substantially as before set forth,of the furnacebody, the open air-pipes running diagonally across the furnace-body and crossing each 0ther at the center thereof, and the cheek-plates for forming a tortuous passage from the firebox to the smoke-exit.

2. In an air-heating furnace, the combination, substantially as before set forth, of the smoke-exit provided With a damper, the horizontal pipes H, leading one from each side 0f the back plate of the furnace-body, the vertical pipes G, leading therefrom and connected at the top with the longitudinal pipes B, the skeleton draft-checks, the pipe D, and the connections G G.

3. In combination, the whole arrangement of furnace-body A, fire-box S, with back of same forming check-plate K, apertures d d d d d d, frontentrance for cold air, k,checkplatesK K, cold-air passages J J, pipes H H, adjustable caps l l, pipes G G, pipes B B C C, draft-cheeks I I, central pipe, D, smoke-exit; E, damper e, and handle Tf, Substantially as arranged and described, and for the purposes set forth.
